This adapter allows you to mount Yashica/Contax lenses on Leica L mount cameras like the Zigma fp and Leica SL. I bought it used, but it's in great condition. Infinity focus and focus in general work perfectly. I'm selling it because I no longer need it. Mount adapter Yashica/Contax Contax Leica Leica M Leica L Lumix Planar
